The last two motors I built I used Comp Cams in them and also their break-in oil Summit Racing sells the oil. No issues so far.

if you have coated the camshaft lobes with a molley past ,just use valvoline 10-30.pre lube and readey to go,change the filter after2-300miles,open the filter no cuttings you are home free. worked fine for me on the last 3ys i did.
